Question

The latent heat of fusion of water is 3.34 x 105 J/kg. A farmer places a barrel containing 1000 kg of water in his barn one winter's night. When the water cools to 0oC, it begin to freeze. How much heat does the water give out while it is freezing until it has all become ice at 0oC?

Question 5 options:
A) 3.34 x 10^8 J

B) 3.34 x 10^3 J

C) 3.34 x 10^6 J

D) 3.34 x 10^4 J

Answer 1

heat=mass*heatfusion=1E3 * 3.34E5

so what is the answer?

Answer 2

Q= mass x latent heat of fusion
Q= 1000x1000x3.3x100000
Q=3.34x10⁸
